Yo-yo



FIG. 1 is a perspective view of a yo-yo showing my new design;

FIG. 2 is a side elevation view of FIG. 1; and,

FIG. 3 is a top plan view of FIG. 1, the bottom plan view being identical.

The broken line is included for the purpose of illustrating the boundary of a portion of the yo-yo that together with the broken line itself forms no part of the claimed design. 

The ornamental design for a yo-yo, as shown and described.
